Xanthosoma sagittifolium, commonly known as Elephant Ear or Tannia, is a tropical plant native to Central and South America. It is known for its large, arrow-shaped leaves and is often grown for its edible corms. The plant thrives in warm, humid environments and is a popular ornamental plant in tropical and subtropical regions.
Xanthosoma sagittifolium requires bright, indirect light and should be kept in a warm, humid environment. Water the plant regularly to keep the soil evenly moist but not waterlogged. It prefers moderate temperatures and high humidity. Ensure good air circulation to prevent fungal diseases.
Oogst
Xanthosoma sagittifolium, commonly known as tannia or malanga, is typically ready for harvest about 7 months after planting. The tubers should be harvested when the leaves start to yellow and die back, indicating maturity. To harvest, carefully dig around the base of the plant to avoid damaging the tubers. Once unearthed, the tubers should be cleaned and dried before storage. It is important to handle the tubers gently to prevent bruising, which can lead to spoilage.
Bodem
The plant prefers well-draining, loamy soil that is rich in organic matter. Ensure the soil remains moist but not waterlogged. Good drainage is essential to prevent root rot.
Kunstmest
Use a balanced fertilizer with an N-P-K ratio of 10-10-10. Fertilize the plant every 4-6 weeks during the growing season to support its growth and development.
Verpotten
Repot Xanthosoma sagittifolium every 1-2 years or when it outgrows its current pot. Choose a pot that is slightly larger than the current one and ensure it has good drainage. Gently remove the plant from its old pot, place it in the new pot, and fill with fresh, well-draining soil.
Voortplanting
Propagate Xanthosoma sagittifolium by dividing the corms. This is best done during the growing season. Carefully separate the corms, ensuring each division has a portion of the root system, and plant them in individual pots with well-draining soil.
Snoeien
Prune the plant to remove any dead or yellowing leaves to maintain its appearance and health. Regular pruning also helps to improve air circulation around the plant.
Toxiciteit
Xanthosoma sagittifolium is toxic to pets and humans if ingested. The plant contains calcium oxalate crystals, which can cause irritation and swelling of the mouth and throat. Handle with care and keep out of reach of children and pets.
